对称核

In 1956, Meiklejohn and Bean observed that field cooled, partially oxidized, Co particles exhibited hysteresis loops displaced along the magnetic field axis.They attributed this phenomenon to the exchange interaction at the interface between the ferromagnetic Co core and the antiferromagnetic CoO shell.

Meiklejohnc 和 Bean 在 1956 年从成长良好的单晶钴与其表面氧化层的微小颗粒，在强磁场下冷却，观察到磁滞曲线不以磁场零点对称，他们将此现象归因於在内部的 Co核与外部的 CoO 壳之界面产生交互影响。
